IMPROVEMENT IN BARBED FENCES.

Specification forming part of Letters Patent No. 205,635), dated July 2,1878; application tiled June 1, 1878.

To all whom it may concern:

Be it known that I, EDWIN HAVENHILL, of J oliet, in the county of Willand State of Illinois, have invented a new and valuable Improvement inBarbed Fences 5 and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and t0 the letters and figures of reference markedthereon.

Figure 1 of the drawin is a representation of a perspective View of mybarbed fence and blank of barb. Fig. 2 is a modification, perspectiveview, and blank.

The nature of my invention relates to the construction of sheetmetalbarbs for wire fences, as will be hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates myinvention.

I confine my invention to Fig. 2, Fig. 1 being a modification.

From a blank, 0, of sheet metal, having a body of rectangular form and atriangular point, d, I cut a V-shaped opening extending from the baseinward. The inner angle of this V-shaped opening is cut out, as shown atm, for the main wire B of the fence to lie in. The portions of the bodyleft after the V- shaped piece has been cut outform the points (1 d atthe base. These points d d are then bent in opposite directions, leavinga barb with three points pointing in three different directions.

In applying my improved device to a fencewire the main wire B passesthrough the rounded opening 00, and the tie-wire, passing over one ofthe prongs d and under the other, secures the barb to the fence in anefficient and easy manner, the wires being twisted, as is usual in suchcases.

Suitable dies cut out the V-shaped piece, and also form the opening aatone operation.

The modification shown in Fig. 1 is formed from a rectangular blank cutout from opposite sides, leaving the rounded seat 00 for the main wire,as in the three-pointed barb.

1 am aware that three-pointed barbs formed from sheet metal blanks havebefore been known. I

My improvement consists in a circular seat to receive the main wire.

I claim as new- The wire-fence barb formed from the blank C,having thepoint d, the points cl (1, bent in opposite directions, and the circularopening 00, to receive the main wire B, adapted to be applied to a wirefence, as shown and specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of three witnesses.

EDW IN HAVENHILL.
